A NOTE ABOUT CARING FOR THIS SHIRT:
White and Black are mortal dye enemies, and their battlefield is your washing machine. To keep your shirt from reverting to a horrible greyish bleed and taking the rest of your wash with it, we suggest the following methods:

Wash your shirt in COLD water. With like colors. Or by itself.

Add ½-1 cup of white vinegar along with your detergent.

Wash your shirt on the "Delicate" cycle.

To make 100% sure nothing bad happens to this shirt and ones in the same load, wash alone by hand using cold water.
